20 Most Recent Porter Cable 332K Quicksand Random Orbit Sander W/ Case Questions & Answers

Hi, Sanders are prone to getting lots and lots of dust inside the unit. The cooling fan makes this problem inevitable. The only way to fix this is to take it apart and and blast it with a pressurized air tool. Hopefully this will bring back some life to your sander. The effectiveness of this procedure is dependent on how well you can remove all of the dust. hope this helps.

You probably did. They are pretty good about their warranty so I would bring it back to the store and get a new one

there is a belt from the motor to the pad that has apparently broken. Go to dewaltservicenet.com and you can download both the parts breakdown and the operators manual. If I have helped you would you please vote accordingly and thank you

It sounds to me that you have used the sander a lot and the vibration has broken a wire or it's about to break on the field windings. The brushes you need to look at to see if worn. But I kind of think wire problem. I had this happen on mine and opened it up to find this is what happened. The sander would be turned on and would not operate until I turn upside down and it would work. This is great if you are sanding upside down but this is just a sign that you are on borrowed time as this will eventually not turn on at all. I was able to fix mine with new wire crimp connection and solder with heat shrink material. If not you can order new field winding if this is what is wrong. Cleaning up the sander won't hurt either. You might want to see what a new sander will cost vs. part. Good Luck!

Just solved my problem with Porter Cable 333 orbital sander which just groaned. I thought the worst. I carefully took it apart on the garage floor and immediately suspected it needed lubrication as the motor turned hard. I used my flexible long plastic tube lubrication and put some on the bottom bearing shaft the best I could. I worked it around and around. I began to feel it turning easier. I applied more oil and kept moving and it became completely free. I put a drop on the top bearing even though it was loose. I put it all back together and it works like new. Lesson: do not look for the worst when a tool quits. Suspect the culprit to be lack of lubrication!!!

how to lube sander

I would take a lok at the switch, sometimes they become full of dirt and make intermittent contact

Look at eReplacementParts.com and the parts diagrams

usually you would need a bearing puller or a bearing splitter to remove bearings, give me the exact brand and model number and I will find a breakdown for the tool and let you know more if needed.

There's a belt in there that may have broken or slipped off its track. That's just about all that can go wrong, unless a bearing seizes. You can see an exploded parts view with part numbers here, and download an instruction manual with some photos here that will help you to sort it out.
If you click on the parts numbers (in the list) you'll be able to check availability and/or order them...There's also a link to service centers if you're not comfortable doing the repair yourself.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!

Go to Dewaltservicenet.com and in the center of the page under needing parts type in your tool model number it will take you to another page and scroll down to the type 1 or 2 and click on it. It will bring up an exploded view of this tool. Why do you think that you need brushes? usually I have to replace the bearings and the brushes are pretty durable. Let me know if I can help further

There is a screw holding the pulley on remove it and what I would do is take 2 screwdrivers and gently pry up from either side, The bearing is generally a loose press fit. You might want to take a look at a breakdown at Dewaltservicenet.com and type in your model number so you can see what it looks like. Good luck

It could either be that the brushes partially burned I would check to make sure your brushes are in good shape and take it out of the helpers pay ;)

I also have a PC Model 136 belt sander. Although I don't do a lot of woodworking, it has proved to be a workhorse when I needed it. I don't have a problem with breaking belts - the last ones I bought at OSH. The problem that has developed with mine is getting the belt alignment adjusted, after a belt change, to not run against the sander body. A little banging (with my hand) will correct the problem. I have serviced it to free up the fulcrum, but it still jams most of the time. This doesn't address your problem, but it is good to hear of someone else who appreciates the fine older tools. Just a further thought - the newer belts I have purchased are bi-directional, e.g., they will run either way. I know that the older belts had to run one way and running them backward could - almost surely would - cause them to break. I won't insult your intelligence to suggest that that might be your problem.

The brushes are not replaceable - it is an entire motor assembly. 1) remove the 2 screws holding the top handle on 2) remove the 2 screws on the top of the housing (front either side of switch) 3) remove single screw holding cord hook (rear side of housing) 4) remove small torx screw in the shaker handle and remove the handle Flip over and using a screwdriver begin to pry the top cover off the housing (easiest to get the front side off first)

any word on type of nailer?

call this company, they have the different types I purchased from them and no complaints https://www.ereplacementparts.com/porter-cable-7800-
